abstract
An experiment was conducted in the field of Department of Nematology located at Instructional-cum-Research (ICR) Farm, AAU, Jorhat during the rabi season of 2015 to estimate the avoidable yield losses in local variety of ivy gourd due to root-knot nematode, Meloidogyne incognita in nematode infested field (374 J₂/200 cc soil). The experiment was laid out in paired plot technique with ten replications. Required quantity of Carbofuran granules @ 3 kg a.i./ha was applied at the spot two days before planting. Ten plots each of 3.0m x 3.5m size were treated and another ten plots were kept untreated control (without Carbofuran application). The results indicated that the loss in yield of ivy gourd was recorded to the extent of 35.09 per cent, when the crop was treated with Carbofuran granules @ 3 kg a.i./ha.
